CodeDay is a nationwide event where student programmers, artists, musicians, actors, and everyone else can get together and build apps & games for 24 hours. Students of all skill levels are welcome — we have workshops and mentors who can help if you're new!

CodeDay is supported nationwide by these sponsors:
